HAND TACKlNG-MACHINE.

SPECFICATION forming part of Letters Patent No. 358,770, dated March 1, 1887.

Application filed July 2, 1886.

To @ZZ whom it may concern:

Be it known that we, PETER A. CoUrAL and CHARLES E. HOLLAND, of Boston, in the county of Suffolk and State of Massachusetts,

have invented certain new and useful Im provements in Hand Tacking or N ailing Machines, of which the following is a specification.

- This invention relates to that class of nailing or tacking machines known as hand-tackro ers, in which a stock or holder is employed which is capable of being grasped by the operators hand and pressed toward that portion of the upper of a boot or shoe which is to be tacked to the inner sole in the operation of i 5 lasting, pressure thus exerted on the stock causinga movable bar projecting therefrom to be thrust into the stock, and by its inward movement to first retract a driver-bar against the pressure of its operating-spring, and then improvements which we will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of this specication, Figures 1 and 2 rep` resent side elevations, taken from different points, of our improved machine, the stock being shown partly in section in each. Figs. 3 and 4 represent side elevations of the operating rod or bar, which projects from the stock and is displaced or pressed into the stock by pressure against the sole. Fig. 5 represents an elevation of the machine from the side opposite to that from which Fig. 2 is taken. Fig. Grepresents asection onliuexm, Fig. 1. Figs. 7 and 8 represent side elevations ot' the driverbar. Fig. 9 represents an end elevation of the same. Figs. 10, 11, and 12 represent perspective views of t-he staple-forming devices at different stages of their operation. Fig. 13

Serial No. 206,951. (No model.)

In the drawings, c represents a stock or handle, formed to be grasped and supported by the operators hand, the stock being preferably somewhat elliptical in crosssection, as shown in Fig. 6. To the upper end of the stock are attached vert-ical plates or supports b b, in which are the bearings for a reel, c, containing a coil of wire, 3, to be converted into staples by the mechanism hereinafter de- 6o scribed.

d represents a driver-bar, adapted to slidein guides in the stoel; or handle, and having a driver, d, attached to its lower end. A spring,

f, contained in a tubular holder, g, on the upper end of the stock, bears on the upper end of the driver-bar.

' c represents an operating bar, which is adapted to slide in guides in the stock, and projects below the lower end of the latter. 7c The operating-bar e is normally depressed by a spring, y', contained in a tubular casing, h, on the upper end of the stock, said spring bearing on the upper end ofthe operating-bar.

In the operation of the device, the operator, 7 5 placing the lower end of the operating-bar against the surface of the upper into which a fastening is to be driven, presses the stock toward 'said surface, thus causing the stock to slide upon the bar, the latter being prevented 8o from moving with the stock. The operatingbar is provided at oneside with a pivoted dog, 7i, which is normally held by a spring, t, in the position shown in Fig. 1, and by engaging with a tooth, j, on the driver-bar arrests the latter while the stock is being depressed, thus, in effect, retracting the driver-bar and driver, and compressing the driving-spring f' until the described depression of the stoel: brings a pin, 7c, thereto attached, into contact with the bev- 9o eled side of an arm, h2, formed on the dog 7L. The dog is tripped bythe contact of said pin and arm, and is thus caused to release the driver-bar, whereupon the spring f forcibly depresses the driver-bar, and causes the driver 9 5 to. force a staple into the upper and inner sole, the staple having been formed, as hereinafter described, while the stock was being depressed. The wire passes from the reel downwardly to the lower portion of the stock, where it is laid roo across a movable block, c', as shown in Fig. 1l, prior to the cutting and bending operations. Two feed-rolls, Zm, within the stock grasp the wire and feed it intermittingly, each movement being sufficient to supply enough wire for one staple. The roll m is loose; but the roll Z has attached to it a ratchet, n, with which engages a pawl, o, pivoted to a lever, p. Said lever is pivoted at q to the stock, and has a tooth, l", on one side, (shown in dotted lines in Fig. 5,) which comes in contact with a pivoted dog, r', on the operating-bar e while the stock is being depressed. Said dog r, by its contact with the tooth r, swings the lever p upwardly and causes the pawl o at the free end of said lever to partially rotate the feedroll Z in the direction indicated by the arrow in Fig. 5, thus feeding the wire and causing its end to lie across the block c', as shown in Fig. 11.

z represents a block or slide, which is fitted to slide upon the driver-bar d, the latter being contained in a slot or way, z', in one side of said block. On the lower end of the block z is formed a diagonal cutter, a', which co-operates with a shoulder, b', Fig. 5, within the stock and at the lower portion thereof in cutting the wire diagonally and forming a staple blank, 2, having pointed ends, Fig. 13. The sides of the slot or way z in the block z constitute benders or formers, which, when the block'z is depressed, as hereinafter described, co-operate with the block c' in bending the blank into staple form, as shown in Fig. 12.

The block z is depressed just after the wire is fed and by the means next described. A rock-shaft, t, is journaled in the stock, and to it are rigidly attached two levers, u o, one of which, u, has a stud or roller on-its outer end entering a vertical slot, w, in the operatingbar, while the other, o, has a stud or roller entering a diagonal slot, y, in a wing or offset on the block z. The described downward move of the stock on the operating-bar brings the lower end of the slot w in said bar into contact with the stud on the lever a. This contact swings the lever u upwardly and causes the lever o to swing toward the operating-bar, the stud of the lever o being thus caused to act on the diagonal slot y and depress the block z with the result above described.' |This depression of the block z takes place just after the wire is fed and before the driver-bar is released.

The block c', over which the staple is bent, is formed on or attached to a yoke, e', einbracing the operatingbar e, the aperture in said yoke through which said bar passes being of sufficient size to permit the yoke and the block c to slide crosswise of the bar. The block c is thus enabled to project under the block z, as shown in Fig. 11, and coincide with the slot or way z therein, as shown in Fig. 12, and is also enabled to be moved back from said block to permit the driver to descend, as shown in Fig. 10.

A spring, g, Fig. 1, normally holds the yoke and its block in the position shown in Figs. 11 and 12. The yoke is moved back to the position shown in Fig. 10 by a cam, f', on one side of the operating-bar, near the lower end thereof. When the stock, in being depressed, reaches the lower portion of the operating-bar, the cam f passes into the yoke, and in so doing presses it back to the position shown in Fig. 10 just before the driveris released, thus leaving the staple in the lower portion of the slot or way z of the block, so that it can be ejected therefrom and driven by the driver.

The operation as a whole is as follows: The operator grasps the stock and, holding the lower end of the operating-bar against the surface into whicha staple is to be driven, presses the stock toward said surface. The operating-bar is thus pushed into the stock and in its movement relatively to the stock raises the driver, and while the driver is rising' first rotates the feed-rolls, thereby feeding the wire, then depresses the block z, thereby severing a blank from the wire and bending it into staple form over the block c', and finally withdraws the block e from the formed staple. The driver-bar is then released and is projected by the spring f, the driver being thus caused to drive the staple. The operator then raises the stock and allows the spring g to move the operating-bar down to its starting position.

During the downward movement of the operating-bar the upper end of the slot w strikes the stud of the lever u and depresses the latter, thereby causing the lever o to raise the block z. When the cam f on the operatingbar leaves the yoke e', the spring g forces the block c against the driver, as shown in Fig. 10, and when the driver is raised above said block by the next depression of the stock the block c is further forced by the spring under the driver and under the block z.
